SWITCH LOCK.

Application led December 30, 1925. -Serial Ho..78,848. My present invention relates to an im; A well known type of manually operated,

proved switch lock for use in connection rotary switch throwing mechanism includes with railway switches, and designed as a the tie rod between the switch rails, the safety appliance for co-operation with the connecting rod 6, which is connected to the i switch points of the standard type of switch stand 7- by crank arm 8, and the 60 switches,\which switch points are connected` operating lever 9 by means of which the and move laterally for opening and closing switch rails are moved laterally in usual the switch. The switch lock is manually manner. operated independently of the switch- In connection with the points of the 10 throwing mechanism and is operated both switch rails I utilize the locking mechanism 66' before and after each throw of the switch. which is intended, except when the switch The switch-lock contemplates the utilizais actually being thrown, to be at all times tion of a pair of connected locking members in locking position with relation to the or blocks, longitudinally slidable with reswitch points, for the purpose of rigidly Y l5 lation to the railway tracks or rails for coholding the switch rails in proper position 70 action with the two switch points, to hold against displacement. Said points in adjusted position. As is The locking mechanism includes a pair well known the standard type of manually of heavy, solid, lock blocks 10 and 11, each operated switch-throwing mechanism, and of which is fashioned with three wedge particularly the connecting rod ortie rod of shaped tongues 12 which form between 75 Such mechanism, is subject to breakage, and them a pair of grooves or recesses 13 and under such conditions one or the other of 13 that are complementary to the points of the two switch points is thus free to be the switch rails 3 and 4. spread open by passing wheels resulting in One of these lock blocks is used at the accidents. The primary object of my ininner side and contiguous to each track rail B0 vention is the provision of a safety device and provided with a lower guide flange 14 or lock for use with the switch tongues at its inner side. The rail plate 15 on which that will hold them at all timesin adjusted the track rail rests and upon which the position, whether the switch is ,open or switch point is movable is fashioned with a closed, against accidental displacement. Z-bar 16 which may be bolted thereto as 85 The invention consists in certain novel shown. combinations and arrangements of parts .as The pair of lock blocks are thus disposed will hereinafter be more fully set forth and on the rail plates and retained between the claimed. track rail at their outer sides and the Z-bar In the accompanying drawings I have ilat their inner sides `in order that they may 90 lustrated one complete example of the beslid back and forth parallel with the track physical embodiment of my invention rails. In normal locked position the blocks wherein the parts are combined and arengage the rail points or switch points as ranged in accordance with the best mode I shown in Figure 2 with the points of the 4 have thus far devised for the practical appliswitch rails fitting snugly into the wedge 95 cation of the principles of my invention. shaped recesses: The tops 'of the lock Figure 1 is a perspective view showing in blocks, as seen 1n Figure 3, are below the detail one of the switch-point locks. ball' of the track rail and below the top of Figure 2 is a plan view showing a standthe switch rail point, to permit passage of ard type of switch with the lock of my inthe flanges of the wheels of rollin stock, 100 vention applied thereto. but the recessed lock blocks or slide olts 10 Figure 3 is a detail sectional view and 11 engage the switch points over an through a rail and switch-rail showing the area suicient to insure a rigid retention of relation of a lock-block to these rails. the points. Thus the properly spaced In order that the general arrangement switch points are at all times maintained in 105 and relation of parts may readily be underthat osition whether the switch is open or stood I have shown in Figure 2 a portion clo of a railway includin'g the ties 1, railway The two slidebolts or lock blocks 10 and rails 2, 2 and switch rails 3 and 4 laterally 11 are joined by a tie rod 17 ri idl secured movable with relation to the track rails, to each slide bolt and the slide olts are 110 slid with a simultaneous movement out of and into engagement with the switch points by actuating the operating lever 18 which is pivoted at one side of the railway track adjacent to the switch operating mechanism for convenience of the trainman or switch man. The pivoted lever 18 is connected to a link 19 and rock shaft 2() journaled in beaings 2l secured to one of the ties and extending under one of the track rails to approximately the center of the track where it is connected by a crank arm 22 thereon and a link 23 to the tie rod 17 of the slide bolts.

In Figure 2 by dotted lines the lock is shown in open position and it will be apparent that by turning the lever 18 to the dotted position at the right. the slide bolts are withdrawn from the switch points in order that the switch throwing mechanism ma be operated to throw the switch. A ter the switch is thrown the lever 18 is turned from dotted position to full line position to cause engagement with the switch points of another pair of notches or recesses of the slide bolts. It will be understood that the slide bolts are movable longitudinally only, while the switch points are of course fmovable laterally of the track rails, and therefore the switch points are engaged by a 'selective or alternate pair of notches or recesses of the slide bolts depending upon the position of the switch points.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is- 1. The combination with a pair of laterally movable switch points v,and track rails, of a pair of longitudinally' movablerslide bolts guided, at the outer sides by said track rails and provided with guides at their inner sides, saidslide bolts each having a pair of recesses for alternate engagement with said points, and means for simultaneously actuatingsaid bolts.

2. The combination with a pair of longitudinally slidable lock-bolts each having a pair of spaced recesses for alternate engagement with switch points, of means for suporting and guiding said bolts, a tie rod etween the bolts, and lever operated mechanism for actuating said bolts.

3. The combinatlon with a ally movable switch rails an and tie plates secured beneath the rails, of a pair o slide bolts having pairs of recesses for alternate engagement with said switch air of latertrack rails rails. said bolts guided at one side by the track rails, guide flanges at the inner sides of said bolts and guide devices for co-action therewith on said tie plates, a tie rod connecting said Vbolts and lever operated mechanism for actuating said bolts.

The pivoted lever 18 is connected to a link 19 and rock shaft 2O journaled in bearings 21 secured to one of the ties and extending under one of the track rails to aproximately the center of the track Where it is connected by a crank arm 22 thereon and a link 23 to the tie rod 17 of the slide bolts.

In Figure 2 by dotted lines the lock is shown in open position and it will be apparent that by turning the lever 18 to the dotted position at the right` the slide bolts are withdrawn from the switch points in order that the switch throwing mechanism ma be operated to throw the switch. Agter the switch is thrown the lever 18 is turned from dotted position to full line position to cause engagement with the switch points of another pair of notches or recesses of the slide bolts. It will be understood that the slide bolts are movable longitudinally only, While the switch points are of course `movable laterally of the track rails, and therefore the switch points are engaged by a selective or alternate air of notches or recesses of the slide bolts depending upon the position of the switch points.
